Insulated concrete forms (ICF) can be used as a substitute for traditional wood framing in building construction. Heating and cooling bills will be about 50% less than in a similar wood-frame home in Vermont. An ICF home will be approximately 10% more expensive to construct than a wood-frame home. A typical 2,000 square-foot home costs $120 per square foot to build with wood framing in Vermont and costs $200 per month (on average) to heat or cool.What is the IRR on the incremental investment in an equivalent-sized ICF home? The home’s residual value with both framing methods in 20 years is expected to be $280,000.
An executive receives an annual salary of P400,000 and his secretary a salary P100,000 a year. A certain task can be performed by the executive, working alone, in 4 hours. If he delegates the task to his secretary t will require him 30 minutes to explain the work and another 45 minutes to check the finished work. Due to the unfamiliarity of the secretary to do the Task it takes her an additional time of 6 hours after being instructed. Considering salary cost only, determine the cost of performing the task by each method, if the secretary works 2,400 hours a year and the executive 3,000 hours a year.

For example, at the beginning of February 2023, FiberOne, a broadband internet provider in Nigeria, was providing internet with speeds of up to 500Mbps, which is fast. The installation fee was N32,231 (about US$70) and the monthly subscription cost around N100,000 (US$220). Starlink in Nigeria, meanwhile, costs about N276,000 (US$599) once- off for the kit and installation, then charges a monthly subscription fee of about [N19,800] (US$43). Starlink is cheaper in the long term than both fibre optic and mobile internet providers. But can an average rural Nigerian household with a monthly income of less than N28,000 (US$60) afford it? Given that average incomes are similarly low in most rural and remote parts of Africa, there's a risk that Starlink's targeted users on the continent won't be able to use the service. The reason that Starlink is able to charge a lower monthly price for their…arrow_forward
